Cortex-M interrupts naming mis-alignment

[tarek-bochkati]

Hello,

Looking into:

• CMSIS/Core/Template/Device_M/Source/startup_Device.c
• CMSIS/Core/Template/Device_M/Include/Device.h

I found these name incoherencies

startup_Device.c	Device.h	ALIGNED	NOT ALIGNED
Reset_Handler	Reset_IRQn	X
NMI_Handler	NonMaskableInt_IRQn		X
HardFault_Handler	HardFault_IRQn	X
MemManage_Handler	MemoryManagement		X
BusFault_Handler	BusFault_IRQn	X
UsageFault_Handler	UsageFault_IRQn	X
SecureFault_Handler	SecureFault_IRQn	X
SVC_Handler	SVCall_IRQn		X
DebugMon_Handler	DebugMonitor_IRQn		X
PendSV_Handler	PendSV_IRQn	X
SysTick_Handler	SysTick_IRQn	X

Is there any reason why these interrupt names (NMI, MemManage, SVC, DebugMon) are not aligned between the 2 files ?

Thank you in advance.

Hi @tarek-bochkati, yes, these names are inconsistent since ages. If we'd change them, we'll end up with inconsistent names across devices. I.e., these files are templates only. The changes would only become effective once device vendors would pick up the updated templates for their device family support. Using different names between vendors and device families would cause trouble porting software between devices.
